Long shot - youngish dogs for adoption? Small - terrier size. Essex/Suffolk area

I know it's a very long shot here, but I was wondering if anyone could help?

My nan is looking for a dog. Fairly young though not necessarily a puppy. Quite small, terrier size. She's not able to pay a lot, so breeders are out of the question. Local dog rehoming centres don't seem to have the type she's after.

She's not fussy, just wants a small dog she can handle at the age of 70. She doesn't want an older dog, as doesn't want to get attached to then lose it.

Sorry, just saw your post about toilet training. A lot of the Many Tears ex-breedng dogs have been kennelled, so would need careful sensitive toilet training, despite not being pups.

To be honest, an awful lot of rescue dogs will need work on toiletting and others may regress and need a refresher course, as it were, when they move to a new home (need to learn where the door is and how to ask to go out etc).

To be honest, when taking on a rescue, you have to be prepared to put in some work with things like that. Some dogs find themselves in rescue through no fault of their own, but many are there because they have issues that the owners were unable or unwilling to work on.

That said, if she went for a dog that had been fostered in a home, rather than kennelled, she would at least have a better idea of how much/little work they need and in what areas.
